Over the course of two and a half years, Dr. Poroger also billed $500 for epilepsy tests at her Queens clinic, allege federal authorities. The problem was, all of those services either weren’t needed or never provided, according to an indictment unsealed today in Brooklyn federal court.

Dr. Poroger, 56, a doctor of osteopathy, was among 12 persons, including three medical doctors and a chiropractor charged for their roles in separate health care fraud schemes that sought to bilk Medicare of about $95 million, said authorities.

The alleged fraud rings operated in Brooklyn and Queens.

Dr. Poroger is the only Staten Islander accused.

"What all these criminal schemes have in common is the exploitation of Medicare," said FBI Assistant Director in Charge Janice K. Fedarcyk, in a statement. "A program to help seniors manage the costs of health care was abused here to line the pockets of unscrupulous doctors and others. Medicare and Medicaid are taxpayer funded, so the outrageous conduct of these defendants victimized everyone."

Ms. Fedarcyk announced the arrests along with federal Justice Department and Department of Health and Human Services officials.

Each defendant, with the exception of Dr. Poroger was arrested or surrendered to authorities today, said officials. A law enforcement source said Dr. Poroger was in Florida and expected to surrender at a later time.

Dr. Poroger’s lawyer, Susan Kellman of Brooklyn, could not immediately be reached today for comment.

The United States attorney for the Eastern District of New York is prosecuting the case.

Prosecutors said Dr. Poroger is the medical director and chief executive officer of North Austin Medical in Queen’s Forest Hills section.

Between November 2006 and March 2009, the clinic billed Medicare about $13 million in bogus claims for services allegedly prescribed or rendered by Dr. Poroger, said court papers. Medicare paid about $4.4 million, those documents said.

Dr. Poroger "repeatedly" prescribed unnecessary medical services and tests, including IV vitamin infusion therapy, sleep studies, nerve conduction tests and EEGs, according to court records. EEGs measure the brain’s electrical activity. One of the test’s uses is to diagnose epilepsy and determine what type of seizures are occurring.

The Medicare payments were deposited into North Austin’s bank account. Dr. Poroger dispersed that cash to herself and others, contend authorities.

She is charged with 14 counts of health care fraud.

The suspects in the other schemes are accused of submitting more than $82 million in phony Medicare claims and laundering money.

Some allegedly paid kickbacks to Medicare beneficiaries to use their names to bill for services not provided or required, such as massages and facials.

Medicare beneficiaries were recruited by offering them lunches and dance clinics, said authorities.
